Safety Considerations (contd)
WARNING
INSTRUCTIONS FOR
ADJUSTMENTS WHILE
COVERS ARE REMOVED
AND FOR SERVICING ARE
FOR USE BY SERVICE-
TRAINED PERSONNEL
ONLY. TO AVOID
DANGEROUS ELECTRIC
SHOCK, DO NOT PERFORM
SUCH ADJUSTMENTS OR
SERVICING UNLESS
QUALIFIED TO DO SO.
WARNING
ANY INTERRUPTION OF THE
PROTECTIVE GROUNDING
CONDUCTOR (INSIDE OR
OUTSIDE THE PRODUCT'S
CIRCUITRY) OR
DISCONNECTING THE
PROTECTIVE EARTH
TERMINAL WILL CAUSE
A POTENTIAL SHOCK
HAZARD THAT COULD
RESULT IN PERSONAL
INJURY. (GROUNDING ONE
CONDUCTOR OF A TWO
CONDUCTOR OUTLET IS
NOT SUFFICIENT
PROTECTION.)
Whenever it is likely that the
protection has been impaired, the
instrument must be made inoperative
and be secured against any
unintended operation.
If this instrument is to be energized
via an autotransformer (for voltage
reduction) make sure the common
terminal is connected to the earthed
pole terminal (neutral) of the power
source.
Instructions for adjustments while
covers are removed and for servicing
are for use by trained-personnel only.
To avoid dangerous electric shock,
do not perform such adjustments or
servicing unless qualified to do so.
For continued protection against fire,
replace the line fuse(s) of the same
current rating and type (for example,
normal blow, time delay). Do not use
repaired fuses or short circuited
fuseholders.
Acoustic Noise Emissions
LpA<47 dB at operator position, at
normal operation, tested per
EN 27779. All data are the results
from type test.
Geräuschemission
LpA<47 dB am Arbeits
platz, normaler Betrieb, geprüft nach

Assembly-Level Service Guide xiii
Preface
This guide provides assembly-level service information for the Agilent 53131A and
Agilent 53132A Universal Counters, and the Agilent 53181A Frequency Counter.
How to Use This Guide
Repair Strategy
This service guide is designed to isolate failures to the assembly level only.
The Agilent 53131A/132A/181A Counter can be returned to Agilent Technologies for
all service work, including troubleshooting, and verifying specifications. Contact
your nearest Agilent Technologies Sales and Service Office for more details.
Note: there is an Express Repair/Performance Calibration Service for USA customers
if downtime is critical. You can receive your repaired Counter via overnight shipment.
Just call 800-403-0801 and ask for Express Repair/Performance Calibration Service.
When your Counter is repaired, it will be returned via overnight shipment at no extra
charge.
If you decide to service the Counter yourself, use the troubleshooting procedures in
Chapter 2 (Service) and the disassembly and reassembly procedures in Chapter 3
(Replacing Assemblies). Then use the calibration instructions in Chapter 2 to
calibrate the Counter for peak-performance operation, and finally perform the
complete performance tests in Chapter 1 to verify the Counter's specifications.
Instrument Identification
Instrument identification is made from the serial number on the rear panel of the
Counter. Agilent uses a two-part serial number with the first part (prefix) identifying a
series of instruments and the second part (suffix) identifying a particular instrument
within a series. An Agilent-assigned alpha character between the prefix and suffix
identifies the country in which the instrument was manufactured.

Preface
xiv Assembly-Level Service Guide
Instruments Covered by this Guide
This guide applies directly to Agilent 53131A, Agilent 53132A, and Agilent 53181A
Counters that have the same serial number prefix(es) shown on the title page. If the
serial number prefix of your Counter differs from that listed on the title page of this
guide, then there may be differences between this guide and your instrument.
Instruments having a higher serial prefix are covered when required by one or more
manual-change sheets included with this guide. If a required change sheet is missing,
contact your nearest Agilent Technologies Sales Office listed at the back of this guide.
Instruments having a serial prefix lower than that listed on the title page are covered
in Chapter 6, “Backdating.”
Assembly-Level Service Guide Organization
This assembly-level service guide consists of a table of contents, preface, eight
chapters and an index. The page running headers identify the chapters and sections of
this manual. The chapter contents are summarized as follows:
Chapter 1, “Performance Tests,” provides procedures that verify the Counter operates
properly and meets the Agilent 53131A/132A or Agilent 53181A specifications given
in Chapter 7, “Agilent 53131A/132A Specifications,” or Chapter 8, “Agilent 53181A
Specifications,” in this guide.
Chapter 2, “Service,” is divided into seven main sections that provide instructions for
returning the Counter to Agilent Technologies for service, calibrating the Counter,
and troubleshooting the assemblies in the Counter.
Chapter 3, “Replacing Assemblies,” provides procedures for replacing defective
assemblies and/or modules in the Counter.
Chapter 4, “Retrofitting Options,” provides field-installation procedures that help you
install options into the Counter.
Chapter 5, “Replaceable Parts,” lists the replaceable parts contained in the Counter,
and explains how to order replacement parts for your Counter.
Chapter 6, “Backdating,” contains information required to adapt this manual for older
instruments.

Description of the 225 MHz Counters
The Agilent 53131A and Agilent 53132A are universal counters capable of
measuring frequencies to 225 MHz on Channels 1 and 2. With an optional Channel 3,
this frequency is extended to 3.0 GHz (Option 030); 5.0 GHz (Option 050) or 12.4
GHz (Option 124).”
For the Agilent 53131A, frequency and time interval resolutions are 10 digits in one
second and 500 picoseconds, respectively. The Agilent 53131A provides users with
a GPIB measuring speed of 200 measurements per second, and is suitable for bench-
top operation and lower-volume ATE operation. The frequency and time interval
resolutions for the Agilent 53132A are up to 12 digits in one second and 150
picoseconds, respectively. The Agilent 53132A provides users with exceptional
resolution, and is ideal for ATE systems operation.
The Agilent 53131A/132A basic measurement functions include Frequency, Period,
Pulse Width, Duty Cycle, Rise/Fall Time, Time Interval, Frequency Ratio, Totalize,
Phase, and Peak Voltage.
The Agilent 53181A is a frequency counter capable of measuring frequencies to 225
MHz on Channel 1. Depending on which optional Channel 2 the counter contains,
this capability is extended to 1.5 GHz (Option 015) or 3.0 GHz (Option 030). The
Agilent 53181A has a frequency resolution of 10 digits in one second.
The Agilent 53181A provides users with a GPIB measuring speed of
200 measurements per second, and is suitable for bench-top and ATE operation.
The Agilent 53181A basic measurement functions include Frequency, Period, Peak
Voltage, and Frequency Ratio (if Channel 2 is installed).
The Agilent 53131A/132A/181A include additional measurement functions and
features that are designed specifically for manufacturing and service applications:
• 1, 5, 10 MHz external reference capability—to match customer’s house standard
(however, the Agilent 53132A’s external reference capability is 10 MHz only),
• optional ultra-high stability , high stability, or medium stability oven oscillators
for high accuracy needs,
